The SCT2651 is 5A buck converters with wide input voltage, ranging from 4.5V to 60V, which integrates an 80mΩ high-side MOSFET. The SCT2651, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) which assists the converter on achieving high efficiency at light load or stby condition.The SCT2651 features adjustable switching frequency from 100kHz to 800KHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size. The converter supports external clock synonization with a frequency b from 100kHz to 800KHz. The SCT2651 allows power conversion from high input voltage to low output voltage with a minimum 130ns on- time of high-side MOSFET.The device offers fixed adjustable soft start to prevent inrush current during the startup of output voltage ramping. The SCT2651 features external loop compensation to provide the flexibility to optimize either loop stability or loop response.The SCT2651 provides cycle-by-cycle current limit, thermal shutdown protection, output over-voltage protection input voltage under-voltage protection. The device is available in an 10-pin DFN-10L package.
